Abstract:
This disclosure relates to a polymer film including: a base film including polyamide-based resin including two or more different kinds of repeat units; and a copolymer including polyamide-based segments and polyether-based segments.
Abstract:
The present invention provides a method of preparing a flame retardant polyester fiber that makes it possible to prepare a flame retardant polyester fiber having excellent shape stability while preventing a lumping phenomonon and reducing powder generation and discoloration during the preparing process of the flame retardant polyester fiber, and a flame retardant polyester fiber prepared therefrom.
Abstract:
The present invention relates to: a method for manufacturing a polymer film, the method including a base film forming step for co-extruding a first resin containing a polyamide-based resin and a second resin containing a copolymer including polyamide-based segments and polyether-based segments; a co-extruded film including a base film including a first resin layer containing a polyamide-based resin, and a second resin layer containing a copolymer having polyamide-based segments and polyether-based segments; to a co-extruded film including a base film including a first resin layer and a second resin layer, which have different melting points; and to a method for manufacturing a polymer film, the method including a base film forming step including a step of co-extruding a first resin and a second resin, which have different melting points.
